a complain received by a customer for the newly 520nm green laser pointer

here is the complain I received from a customer:

This is a comparison between what used to be a 200mw red laser. 5mw of green is much brighter than this.

and he gave me two pictures as comparison.



from the picture. the so called red laser module is nearly the same brightness as our green laser pointer.

the green laser pointer we produced newly is 520nm laser diode in. the output is 5-10mw

since the buyer has very high expect for this green laser, I do put the case here. hope someone in this plat-forum can help him compare the two lasers within two different wavelength
